In a patient with a 25‑mm tight distal esophageal stricture extending to the gastro‑oesophageal junction and a small lower esophageal diverticulum, who previously underwent Heller myotomy, is repeat Nissen fundoplication and Heller myotomy indicated?

Repeat Heller Myotomy and Nissen Fundoplication is NOT Indicated

In this patient with a tight distal esophageal stricture following previous Heller myotomy, the primary treatment should be endoscopic dilation, not repeat surgery. Repeat Heller myotomy is technically challenging and carries higher morbidity in previously operated fields, while the stricture itself is best managed endoscopically 1.

Primary Management Strategy

Initial Approach: Endoscopic Dilation

• Perform serial endoscopic dilations as the first-line treatment for this post-surgical stricture 1, 2
• Start with wire-guided balloon or bougie dilators, limiting initial dilation to 10-12 mm diameter given the tight nature of the stricture 1
• Use fluoroscopic guidance given the complex nature (post-surgical, presence of diverticulum, location at GEJ) 1
• Plan weekly or two-weekly sessions until achieving passage of ≥15 mm dilator with symptomatic improvement 1

Adjunctive Therapies if Refractory

If the stricture proves refractory to standard dilation (requiring >5 sessions or inability to maintain 14 mm diameter for 4 weeks):

• Intralesional steroid injections (triamcinolone 40 mg/mL in 0.5 mL aliquots to four quadrants) 1, 2
• Consider endoscopic radial incision (ERI) or needle knife incision 1, 3
• Temporary stent placement in highly refractory cases 2

Why Surgery is NOT the Answer Here

Technical and Risk Considerations

The presence of previous Heller myotomy creates several problems for repeat surgery:

• Adhesions and altered anatomy from prior surgery significantly increase operative difficulty and complication risk 4
• The small lower esophageal diverticulum complicates surgical dissection planes
• Repeat myotomy in scarred tissue risks perforation and inadequate myotomy

The Stricture Etiology Matters

This stricture is most likely reflux-related rather than achalasia recurrence, given:

• The patient already had myotomy (LES should be disrupted)
• Presence of stricture suggests chronic reflux injury post-myotomy 3
• The intervening diverticulum suggests motility issues but not necessarily recurrent achalasia

Critical distinction: If this were true recurrent achalasia with elevated LES pressures on manometry (>15 mmHg), then POEM or repeat myotomy might be considered 5, 3. However, a post-myotomy stricture with normal/low LES pressures indicates reflux disease, not achalasia recurrence.

Essential Diagnostic Workup Before Any Intervention

Before proceeding with any treatment, obtain:

1. High-resolution esophageal manometry - to differentiate reflux-related stricture (low LES pressure 2-5 mmHg) from true achalasia recurrence (elevated LES >15 mmHg) 3
2. Upper endoscopy with biopsy - assess for eosinophilic esophagitis, exclude malignancy, evaluate reflux severity 1
3. Barium esophagram - define stricture length, angulation, and diverticulum anatomy 1
4. 24-hour pH monitoring (if feasible) - quantify reflux burden 6

If Surgery Were Eventually Needed

Only after failed endoscopic management (multiple dilations, adjunctive therapies) and confirmed diagnosis would surgery be considered:

• NOT repeat Heller myotomy - the myotomy is already done
• NOT Nissen fundoplication - this causes unacceptably high dysphagia rates (15%) in aperistaltic esophagus 6
• Consider partial fundoplication revision (Dor or Toupet) only if severe reflux is documented and contributing to stricture 4, 6, 7

Surgical Approach if Absolutely Required

• Laparoscopic exploration to assess previous myotomy adequacy
• Revision to partial (Dor) fundoplication if wrap is disrupted or causing obstruction 4, 6, 7
• Address the diverticulum only if symptomatic (diverticulectomy with myotomy extension and Dor fundoplication) 8, 7, 9

Critical Pitfalls to Avoid

1. Do not assume this is recurrent achalasia - get manometry first 3
2. Do not rush to surgery - endoscopic management succeeds in >95% of post-surgical strictures with appropriate technique 1
3. Do not perform Nissen fundoplication in any patient with esophageal dysmotility - dysphagia recurrence is 15% vs 2.8% with partial fundoplication 6
4. Do not ignore the diverticulum - but also don't operate on it unless it's symptomatic or enlarging 8, 7

Practical Algorithm

1. Manometry + endoscopy → Determine if reflux-stricture vs recurrent achalasia
2. If low LES pressure (reflux-stricture): Serial dilations + PPI therapy 1
3. If refractory after 5+ sessions: Add steroid injection or ERI 1, 3, 2
4. If still refractory: Multidisciplinary discussion for possible stent or surgical revision 4, 2
5. If high LES pressure (true recurrence): Consider POEM as preferred over redo-myotomy 5

The 25 mm stricture length and presence of diverticulum make this a complex stricture requiring experienced hands, but endoscopic management remains first-line with excellent success rates when performed systematically 1.
